Solve these inequalities.
(ii) 3^x +5 bigger or equal to 32
Please help! I don't know how to solve this though I a aware it involves logarithms. Please show me what to do and explain why.

Best ResponseYou've already chosen the best response.1\[\huge\rm 3^x +5 \ge 32\] yes right you have to take log both sides but first move `5` to the right side and then take log

Best ResponseYou've already chosen the best response.0So It would be \[3^{x} \ge 17\] ? How do I take log of both sides?

Best ResponseYou've already chosen the best response.0ok so after \[3^{x} \ge 27\] how do I take log of both sides?

Best ResponseYou've already chosen the best response.1yes right now take log both sides and apply the product rule \[\huge\rm log (3)^x \ge \log(27)\]

Best ResponseYou've already chosen the best response.0Ok I am new too logarithms so sorry for taking so much time. If you use the power rule does that mean that I move the exponent x in front of the first logarithm?

Best ResponseYou've already chosen the best response.1yes right :=) and its okay take ur time!

Best ResponseYou've already chosen the best response.0Thanks! All right so, \[x \log_{}3 \ge \log27\]

Best ResponseYou've already chosen the best response.1yes right now to solve for x you should move log(3) to the right side :=) and then use calculator :P that's it!
